This invention relates to sash operators, :such :as the braces or holders employed for holding gstorm'sash-and screen I sashin different positions .in;-.a window .frame.

.Generally stated, .the object :of :the invention ;ispto:.provide .anovel and improved construction -.-and;arrangement whereby the .pivot or swivel of the operator or brace, on the window'frame, is of an improved :nature orform, so thatthe oper- :-:at0r and its pivot. or swivel can be readily. detached from thepivot bracket-on thewindow -frame, by adjusting a retainingdevice about :an 'axis at-rightangles tothe axis of .thersaid pivot :or swivel, whereby the-saidbracket, does not need lobe-removed when the sash-,isi-taken .out of the window frame, but instead is permitted to :re- ;main in position where itis fastened thereon, ,and so that the said pivot or swivel is :again easily restored to operative condition .when-the sash is againplaced in position in-the :window frame.

.It is.also an object to provide pertain-details ,and; specific features of construction tending to increase the general efl'iciency and-desirability ,of aw-indow sash operatoror-bracepivot ,or swivel of this. particular character.

.To the foregoing and other useful .ends, .the invention consists in ,matters hereinafter set .forthandclaimed; and shown in the accompanyingdrawing, in which- .Fig. 1.is a perspective of .a window frame provided with a sash anda sashoperator pivot or swivel, of a separable nature, ,on-the window frame, embodying the principles of the invention.

Fig. 8 is aperspective view showingtheparts of the pivot or swivel plate separated.

-As "thus illustrated, the invention comprises a pivot =or swivelbracket or plate I fastened to the window frame 2 *byscrews inserted through the holes =3 formed in the upper and lower ear portions'of'said -bracket,'the latter being preferably of metal-pressed into the desired form'to provide -a=recess-or-chamber '4 between the middle of the plateand the side surface of the window frame. The bulging outer wall 5 of the said plate or bracket is provided with a round opening 6 'formed therein, not centrally, but rather-off centeryas shown more clearly in Figs. 4 and5,

- where it will be seen'that the said round hole or opening 6 is displaced laterally so that it is nearer the left-hand edge of the plate orbracket '-I,-than it is the right-hand edge thereof. A pin :1, -made, for example, of heavy wire, extends -vertically-in the openings 8 formed'in the upper andilower-horizontally disposed portions!) and all)v of-said plate or bracket. 'The upper end of said'pin is provided with a horizontal or'laterally :bent-portionl I, forming a handle, and the lower end portion I2 of the pin is pinched or-upset to prevent it from being pulled up vertically'out of .the bracket. It will be seen that the said pin 'I isladapted to rotate about a vertical axis, which latter :practically coincides with the right-hand edgeof 'thehole or opening 6, as indicated more :clearly inFigs. 4 and 5 of the drawing. On the side of the .pin facing away from the handle, there is a-ourved notch 13 thatis curved onthe linerof the circlexof the opening 6 formed in the bracket.

The so-called sashioperator, which is in the natureof abraceiorholder, maybe of any suitable known or desiredconstruction, but as shown it comprises-the duplicate links I4 and I5 swiveledor pivoted together at l6 forming atoggle jointwhere their ends meet at apoint about midway between the opposite ends of the said brace or holder. The outer end of the operator. is .pivoted at: H on a bracket l8, which is fastened by screws to the sash I9, which latter may be either -.a.screen sash or a-storm sash, or any kind of sash. .Theinner end of the said operator or sash .holder is provided with .a-rigidpivot or swivel =20, the .-enlarged .head of which latter projects through the hole 6 when the sash operator is in use, and which is provided within the cavity 4 with a circumferential groove 2|, which is preferably curved on the line of the circle formed by the circumference of the pin 1 previously mentioned. See Figs. 6 and 7 of the drawing. The head of the pivot is the same in diameter as the hole 6 which forms the bearing for the oscillatory pivot.

Therefore, when the adjustable pin I is in the position shown in Fig. 5 of the drawing, the hole 6 is not obstructed, and the pivot or swivel may be inserted through this hole until the inner side of the link I5 is flatwis against the wall 5 of the bracket or swivel plate. Then, when the pin 1 is adjusted to the position shown in Fig. 4 of the drawing, the notch I3 is thereby turned around to the other side, and the cylindrical surface of said pin enters the groove 2| and thus locks the pivot or swivel 20 against any outward displacement from the bracket. Then, when it is desired to remove the sash from the window frame, or to perhaps remove the operator or brace bodily by itself, all that is necessary is to again turn the said pin 1 back to the position shown in Fig. 5 of the drawing, for in this position the notch 13 is in alignment with the hole 6, as shown in Figs. 5 and 7 of the drawing, and the swivel or pivot 20 can be pulled outwardly from the bracket or swivel plate, by flexing or springing the brace laterally toward the other side of the window. Thus, the pivot or swivelretaining pin '5 is adjustable about an axis which is preferably vertical, and which is desirably at right angles to the axis of the pivot or swivel 20 of the brace or holder that forms the so-called sash operator.

It will be understood that by adjusting the said brace or sash operator into different positions, it can be used to swing the sash outwardly or inwardly, or to lock the sash in its vertical position in the window frame, or to release the sash from said position, and it is for these reasons that the said sash operator is desirably pivoted to swiveled in a bracket secured to the window frame, in such position that the saidlefthand edge of the bracket or swivel plate is preferably against or quite close to the inner surface of the sash, when the latter is in vertical closed position, as indicated more clearly in Fig. 2 of the drawing.

It is important to observe, of course, that the enlarged inner end of the stud 20 forms a head which has the same diameter as the hole 6 that forms a bearing for the oscillatory stud or pivot. In this way, the said pivot is pulled out by simply flexing the rigid but flexible and springy jointed brace toward the other side of the window. The jointed brace thus formed is sufficiently rigid to do the required work. The bent or formed angle on each of the two duplicate bars and 1 15 makes the operator rigid in any position thereof. When folded, it will not take any more room than others that are made lighter and of much less weight. Either link IE or [5 can be pivoted on the sash and either link can be swiveled 0n the window frame, so that identically the same parts can be assembled at either the right or left brace or operator to be used as either a right or lelft side of the window. The sash operator will not collapse while in the open position, and there will not be any danger of having a finger pinched. When the operator is detached from the house, the bracket-plate has no objectionable projections thereon. The simple action of fastening the arm to the side plate on the window frame with the bent wire locking device makes it simple and trouble-proof and gives it more than ample strength to make it durable and lasting. The toggle-joint at It looks just a little above center, so that the brace is rigid and effective in the fully open position of the sash. The locking pin I, it will be seen, is fixed and immovable and is stationary, except that it can be adjusted about a vertical axis, and this pin not only extends through the chamber provided between the wall 4 and the window frame, but also extends through the top and bottom walls 9 and [0 of the bracket-plate. The bracket-plate l is not movable, but to the contrary is fixed in a stationary position on the window frame.

It is important to observe that the upper and lower bearings 8 on the bracket I are widely spaced apart and that hence the greater portion of the length of the retaining pin I has no engagement with the bracket plate and that in the same way the greater portion of the cylindrical inner head of the stud 20 has no engagement with the bracket plate, so that the greater portions of both the pin and the stud are free and unengaged within the chamber formed on the inner side of the bracket plate.

What I claim as my invention is:

l. A device of the class described comprising a sash brace and a bracket plate adapted to be fastened in stationary position to a window frame providing a chamber between the frame and an outset vertical wall of the plate, said chamber being open at its front and rear sides and having top and bottom walls, an oscillatory andcylindrical pivotal stud mounted adjacent one end of the sash brace rotatable about a fixed axis in a bearing in said vertical wall so that the greater portion of the stud within the chamber is free from engagement with said plate, and a vertical retaining device extending through said chamber comprising an upstanding rotatable member journalled within the top and bottom walls and having a portion extending through said chamber in juxtaposition to said pivot stud, said pivot stud having an annular recess formed therein and a peripheral portion of said rotatable retaining member extending into said recess to prevent axial movement of said pivot stud while permitting unimpaired rotation thereof in the journal, a peripherally disposed portion of said rotatable retaining member being cut away and operative when the retaining member is rotated to bring said cut away portion opposite the stud to permit the stud to be freely withdrawn.

2. A device as defined in claim 1 wherein said rotatable retaining member is provided with a manually operable handle portion disposed outwardly beyond the upper wall of the bracket and extending transversely thereto, said handle being adapted to reside in substantial parallelism with an adjacent fastening flange when the stud is retained against axial displacement and being adapted to reside in a position removed and in substantial parallelism with said flange when the cut away portion of the retaining member is adjacent said stud.
